Two schools in this directory carry full Council of International Schools (CIS) accreditation — Garden International and Regents Pattaya. CIS is a five-year cycle of external review covering governance, learning outcomes, student welfare, child protection, finance, and facilities. Garden's differentiators beyond the shared CIS credential: a published 100% IB Diploma pass rate in 2023, and founding membership of FOBISIA — the regional British-school sports and debate circuit.
Garden runs the IB Diploma Programme at Sixth Form and has reported a published 100% Diploma pass rate in 2023 (per Garden Rayong’s examination-results page). IB pass rates internationally hover in the 78–82% range, so 100% in 2023 (per published results) indicates a school that's either selective at entry or supports rigorously through the two-year programme (or both). The trade-off versus Regents Pattaya at Sixth Form is that Garden runs only the IB Diploma — there's no A-Level alternative.
Garden is one of the founding member schools of the Federation of British International Schools in Asia. FOBISIA is the regional sports, debate, and Model UN circuit. Founding-member status means Garden students travel for inter-school competitions across Bangkok, Singapore, Kuala Lumpur, Phuket, Vietnam, and Indonesia in a way that students at non-FOBISIA schools simply don't.
Ban Chang is a Rayong-province sub-district about 30 minutes south of central Pattaya, immediately east of U-Tapao airport. For Pattaya families, this is a real commute — daily school bus, not walkable. Garden publishes bus fees of ฿18,000–฿32,100 per term depending on zone (roughly ฿55K–฿95K per year per child).
Garden publishes fees per term, not per year. There are three terms in a standard school year (Foundation through Year 10), but Year 11 IGCSE and Years 12–13 IBDP run only two terms because exam sessions cut the academic year short. So when you compare Garden's headline numbers to Rugby's or Regents's per-year figures, multiply Garden's term fees by three for normal years and use the published two-term totals for exam years.
Regents has Sixth Form optionality (IB and A-Level), the Nord Anglia global network, and is geographically closer to Pattaya. Garden has CIS accreditation, a stronger published IBDP track record, and FOBISIA founding-member status. If your child is locked-in IB and external academic credentials matter most, Garden edges Regents. If you want curriculum flexibility at 16 or you'll move countries during the school years, Regents edges Garden.
Rugby is more expensive (฿975K top-end vs Garden's ~฿500K equivalents), has boarding from age 10, runs A-Levels only at Sixth Form, and has the strongest published facility list. Garden is roughly half the per-year cost at peer year-groups, day-only, and IBDP-only. For an IB-pathway family on a tighter premium-tier budget, Garden is the substantially cheaper academic pick.
It is worth dwelling on the CIS credential, because most parents read "accredited" as a binary and it is not. Council of International Schools accreditation is the most demanding generalist standard an international school can hold: a self-study of a year or more, an on-site visiting team, and re-evaluation on a five-year cycle across governance, teaching and learning, child protection, staffing, finance, and facilities — with published standards the school must evidence, not assert. Plenty of schools on the Eastern Seaboard describe themselves as "internationally accredited" on the strength of a curriculum licence or an exam-centre registration. Only Garden and Regents in this directory hold the full CIS mark. For a family choosing between brochures that all use the same adjectives, that distinction is one of the few externally verified separators available — and it is precisely the kind of thing a school cannot buy or improvise in the year before your tour.
Garden's per-term invoicing makes the lifetime cost easy to underestimate, so run it once properly. A child entering Year 1 and graduating through the IB Diploma spends thirteen years on campus; at current published rates that is in the rough order of ฿4.5M–฿5M of tuition, before annual increases — plus the bus. The bus line deserves respect: at ฿55K–฿95K per year per child depending on zone, a Pattaya-based family with two children pays ฿1.4M–฿2.4M in transport alone over a full school career, which is the price of several years' tuition at an Established-tier school. The clean way to think about it: Garden at Pattaya distance costs meaningfully more than Garden at Ban Chang distance. Families who relocate to Ban Chang or Phoenix-area housing estates — many do — buy the school at its true list price and convert two daily bus hours into childhood.
One: the 100% Diploma pass rate is published for 2023 — ask for the full multi-year table, the average point score, and the cohort size each year. A 100% rate from a cohort of twelve means something different from a cohort of sixty, and average points (the IB's real currency for university admissions) matter more than the pass binary. Two: what is the entry policy into the Diploma — open to all Year 11 completers, or gated on IGCSE results? The answer tells you whether the pass rate reflects teaching or selection. Three: which FOBISIA events did teams actually attend last year, and at what additional cost per trip? Four: current class sizes by year group, and the school's stated maximums. None of these are gotcha questions; a school with Garden's paper record should answer all four without blinking.

If you're an IB-pathway family and you want a school whose academic quality has been independently audited by an external body — Garden is the academic pick on the Eastern Seaboard. The CIS five-year audit cycle gives you something every other school here either doesn't have or doesn't publish; the FOBISIA founding membership gives your child a real regional sports + debate circuit; the 100% IBDP track record is comparable to any Bangkok premium. The right family has a child who'll thrive in a structured IB programme, is comfortable above ฿500K/yr at Sixth Form, and either lives in Rayong / Ban Chang or is fine with the 30-minute daily bus from Pattaya.
